COLUMBUS, Ohio — The family of a Texas nurse who flew to Ohio and was diagnosed with Ebola says doctors no longer detect the virus in her body.

A family statement released Wednesday through a media consultant says officials at Emory University Hospital and the Centers for Disease Control and Prevention couldn’t detect Ebola in Amber Vinson as of Tuesday evening. Doctors usually do two tests a day apart before saying they can’t detect the virus. It’s unclear how many tests Vinson has had.

The statement says Vinson’s mother spoke to her Wednesday and Vinson has been approved for transfer from isolation.

Vinson is being treated at Emory, near Atlanta. Emory officials won’t comment on her status.

Vinson helped care for a Liberian man with Ebola who died at a Dallas hospital Oct. 8. Another nurse there also became infected.
